Makita 123910-5 Spare Part - GEAR ASSY DF001D

Makita 123910-5 — Gear assembly / gearbox (original Makita)

Description:

This is the original Makita gear assembly (part no. 123910-5) used as the gearbox/gear assembly in Makita in‑line cordless screwdrivers. It’s the complete gear train assembly that engages the motor pinion and spur gears to deliver the tool’s drive reduction and smooth bit rotation — a direct replacement listed for the DF001D/DF001DW.

What you’re getting:

- Genuine Makita gear assembly, ready to drop into the motor housing and restore the mechanical drive that wears or fails over time.

- The assembly corresponds to the gear group shown in the DF001D/DF001DW parts diagram (it replaces the individual spur gear and motor‑pinion items when fitted as the complete assy).

Fits (example models):

- Makita DF001D / DF001DW (3.6 V in‑line cordless screwdriver series).

Why choose this part:

- Precision fit for the DF001 series so you won’t need to modify housings or other internals — it restores the original gear engagement and runout characteristics.

- Listed in Makita parts breakdowns as the gear assy, so it’s the correct replacement when the gearbox is the failure point.

Note:

This is listed among Makita spare parts for the DF001 family and is the specific gear/gearbox assembly you want if the drive train (gears or pinion engagement) is noisy, slipping, or seized. If you’re repairing your screwdriver, replacing the 123910-5 gear assy will return correct mechanical drive without altering the electrical or housing components. Also useful to keep on hand with other small parts when doing repairs — it’s one of the standard parts used in parts for power tools maintenance.
